I don't follow the bloke, and don't take much notice of what info he puts out, so I've no idea if he breaks it, or just hoovers it from elsewhere. However, whilst in the top division, I seem to remember lost of whinges about stories being leaked/planted released by agents.
I see little reason in a buying club leaking info re transfer targets to the press, as it's only likely to attract other bidders and possibly put up the price.
I only started following him after we got relegated from the Prem so i can't comment at all on what he was like in the Prem for reliability. But over the past 8 years or so he's been remarkably accurate overall, i used to think it must be a network of agents giving him bits but he got so much so much right for so long, including stuff agents wouldn't know i started to think it must a direct line from within the club (until recently when he's still getting bits but nowhere near what he previously got).
I agree that i don't think the club would've sanctioned any leaks though, but it seems the club couldn't work out who it was either to ever stop them.
